Kind of stupid for someone to just full on stop but this is a good reason people need to say something if they are going to grab a wheel. I frequently pass people and find when cornering or when I check traffic behind me, surprise I have someone on my wheel. I don't have a problem if they let me know they are there so I can signal and take precautions but if you are silently behind me who know what can happen. At best a snot rocket in the face.
